Bruins Head Coach Claude Julien informed reporters after Saturday’s practice sessions that first round draft pick David Pastrnak tweaked his shoulder during the morning session.

“As far as I’m concerned he’s day-to-day, and we’ve still got some time before the start of the regular season,” said Julien. “We’ll see when he’s ready to come back. It’s not a dislocated shoulder or anything like that. It’s some kind of a bruised shoulder, so we’ve got to wait to see how it heals.”

Pastrnak left Saturday’s morning session after falling into the boards after colliding with defenseman Matt Bartkowski. Pastrnak did not play in Sunday’s scrimmage and is not expected to appear in Tuesday’s preseason game against the Montreal Canadiens, though the team still holds hope that he will appear in a few preseason games.

The 18-year-old Czech native has been playing right wing on David Krejci’s line for the start of camp. With a major presence in both development and rookie camp, the possibility of Pastrnak making the roster isn’t that far-fetched. Whether or not his absence will affect his chance of making the team, Julien doesn’t know.

“I have no idea, you’d have to ask the GM that,” said Julien. “As far as I’m concerned he’s day-to-day, so whenever we see him back, we’ve still got some time before the regular season, but you can’t control that, and we’ll see when he’s ready to come back.”

Pastrnak has had quite the buzz around him since being invited to training camp. Despite his offensive skill, the forward weighs in at 170 pounds; his size has been a concern from the start, and this injury is doing nothing to quell that.
